We empower scientists and businesses with spectral vision solutions for cleaner, safer decision-making.
Technology
Beyond Intensity - Only Imaging
Traditional cameras measure the light intensity but cannot extract spectrum and polarization information.
Multispectral imaging is rapidly becoming the standard as it improves functionality, speed, throughput, and cost efficiency across cameras and sensing platforms.
Our approach integrates:
-
Passive multipass filtering combined with broadband LCTF.
-
Dual liquid-crystal retarders that mutually compensate dispersion
-
Polarization independent solutions: Special LC devices such as Annular SLM, OASLM, Tunable scattering devices.
Complexity
Richer Data from the Same Scene
By controlling wavelength and polarization, each captured image encodes additional physical information beyond color or brightness.
Example:
Chromophores in skin lesions absorb blue and green wavelengths differently than red and near-infrared, enabling enhanced contrast and material discrimination.
Polarization imaging further reveals collagen fiber structure and orientation, offering insights not accessible through intensity-based imaging alone.

Open Gaps in Existing Optical Technologies
Limitations of Liquid Crystal (LC) Waveplates
-
Wavelength-dependent polarization control
Effective only over narrow bands (~10–50 nm) -
System complexity
Requires spectral filters or multiple narrowband light sources -
High cost & integration burden
Dedicated controllers often exceed $1,000
Limitations of Liquid Crystal Tunable Filters (LCTFs)
-
Low optical throughput
Less than 30% transmission in the target spectral band -
Bulky form factor
Difficult to integrate into compact optical systems -
Limited tuning range
Typically constrained to VIS or NIR -
Slow tuning speed
-
Bandwidth tradeoffs
-
Variable bandwidth: 15–55 nm (~$6–8K)
-
Fixed bandwidth: 13–24 nm (>$16K)
-
Core Tradeoff in Current Solutions: Throughput ↔ Bandwidth
Existing technologies force a compromise between high transmission or narrow spectral control but not both at once.
Why Photoliqsys Is Different
Current LC-based technologies force compromises between bandwidth, throughput, speed, and system complexity. Photoliqsys was built to eliminate those tradeoffs.
